Re: Finding screw for old 28 hp Evinrude 1964.
This is the challenge of working on old boats: you encounter something that a PO did wrong and assume it's correct, and then work around it.
You also find that a PO rigged something different that is nonetheless a proper alternative, but now your motor doesn't match the diagrams, and you get this conversation:
Owner: it's set up like X
Mechanic: Can't be. OMC never did that.
O; but it is
M: impossible
O: take a look
M: well, I'll be....
And then, with old ones, the motor set-up don't always match the diagrams. Klieghaffer and his old mercuries could be quite contrary.
And finally, the "One Piece at a Time" syndrome: someone put a 19XX head on a 19YY lower unit with 19ZZ carbs--and it runs fine. But try to order parts!
